In my previous post, I shared how to predict using a single criteria leveraging machine learning in Python. If you haven’t read that, be sure to read that first here to get a better understanding of what we’re trying to do. In this post, I’ll let computer predict something based on multiple criteria. For example, […]

Machine Learning in Python (Univariate Linear Regression)
In this post, I share a method to utilize Machine Learning using Python. I have collected some data from CDC site about birth rate in the USA over several years. What I’d like to show you is how we can predict birth rate for a year that is NOT present in the dataset. For example, […]
Make a computer guess your word – Python
You’ve undoutedly played games like hangman or seen TV games such as Wheel of Fortune where you’re supposed to guess a word by only given the number of letters (or their placeholders, blank tiles) in a given number of tries. You may have also written similar games yourself. In this post however, I’m going to […]
Words to numbers challenge – Python
In this blog I share techniques on how to convert a dataset containing words into actual numbers (integer or float) save the output with numbers to an external CSV/XLSX data file. If you’re wondering why would one ever need this? Here’s a scenario: A list of movies and their corresponding revenues were read into a […]
General Tree Data Structure – Python
In this post, I’ll demonstrate implementation of what’s known as a General Tree (not binary tree…that’ll be discussed soon in a different post)…it’s a unique data structure that Queue or Stacks cannot easily handle or at all. The key characteristic of this DS is that it allows for hierarchical data representation and relationships…think, taxonomy. Real-world […]
Multi-threading in Python
Most of the python code you encounter while searching online is single-threaded and in most cases, it’s perfectly fine. Such programs has one main thread in the code and it may call various functions one after another or conditionally…the cpu will execute the code in each line of code one after another until the program […]
Queue and Stack Data Structures — Explained
Hi visitors! This post is about explaining the very essential data structures such as Queue and Stacks in a simple way, and provide you with some animations to help. Then I’ll explain how you can implement either data structures in a real-world situation using Python (or any other language, once you understand these fundamentals). I […]
Array of dictionaries – Python datastructure
The internet is littered with simple examples of dictonary object examples in Python. Interestingly, they are all the same copy/pasted code with the same old tired examples and bad coding styles 😂. What we need is examples of more complex, real-world data structures that are more practical. In this blog, I share some valuable techniques […]
Text-to-Speech (TTS) and Pandas (POTUS data)
In this post, I introduce you to my Python 3.x program that reads an external data file containing all president names of the USA to-date (2022), and that allows users to enter a query to and hear the names of presidents as the result. The query can be a number such as a first N […]
Working with 2D Arrays in Python and Graphics
In this post, I’ll share tips on how to create a 2D array and map it to a visual grid to depict it using Python. 2D arrays (or 2D lists as they’re called in Python) are fundamental to any programming language and tackling them requires understanding language-specific syntax, however, the core concepts are the same […]
